Setup (continued)

Setup Input Signals

Step 3:

3a: Set the signal generator amplitude to 500 mV.

NOTE:

The signal generator amplitude can vary from 75 mV to 900 mV to produce a 400 mV DUT

output.

3b: Set the signal generator offset to 660 mV (the center of a nominal RSECL PECL out-

put).

NOTE:

information.

3c: Set the generator output for a PRBS data signal, or for a square wave clock signal with

a 50% duty cycle.

Connect Output Signals

Step 4:

4a: Connect the outputs of the device (Q0, Q1,

…) to the Oscilloscope. The oscilloscope

sampling head must have internal 50

W termination to ground.

NOTE:

Where a single output is being used, the unconnected output for the pair

must be terminated to
